I read the trouble shooting guide But

This is a grand daddy purple that has these brown splotches on some of its leaves I am growing in super soil so I haven't been worried about PH but I think that's the only thing it could be but before I jump in on that Has anyone else seen this none of my other plants have any signs of this and they are all in the same soil

I've seen and currently have one like that. If the pH is too low in the it will do that. Or it's just lacking calcium or magnesium. So it's either it can't get it or it's not there.

Actually either magnesium or potassium. Calcium shows up first at the top.

They say magnesium will quickly stop with foliar spray of Epsom.
